| Subject: | 912UL rough at around 4000 |
My 912UL with 185 hrs. runs rough at the range between 3900 and 4100 rpm. Above
and below rpm's as well as idle are OK.
It has always done it since I got the plane with 150 hrs. TT.
Any suggestions ??
Thanks

Mine runs rough between 4000 and 4200 RPMs...if you find out what causes this,
let me know. I have 288 hours on mine.
Also, I've noticed that lately (maybe because it's getting colder here in the North-West)
that if I quickly advance the throttle from a mid-range setting that
my engine sputters for about 2 seconds before it picks up.
I've checked the float levels and the diaphragms in the Bing carbs....all normal.
If anyone has a suggestion about the hesitation, please let me know. Thanks.
Regards,
Sonny W.

Check the jet needle settings. These govern midrange RPM mixture. Our 914
was incorrectly set from the factory. Perform mag drop per the manual.
Check spark plug boots for corrosion. Good luck!
